Figure 3 Subgroup comparisons of the one-year survival rates among patients who were treated with beta-adrenergic blocking agents with those who were not treated with beta-blockers at the time of percutaneous coronary intervention (PCI). ACC/AHA = American College of Cardiology/American Heart Association; CABG = coronary artery bypass grafting; CAD = coronary artery disease; CHF = congestive heart failure; CI = confidence interval; COPD = chronic obstructive pulmonary disease; LVEF = left ventricular ejection fraction; MI = myocardial infarction; NYHA = New York Heart Association; SVG = saphenous vein graft.
